CAR ATTACHMENT.

Specification of Letters Patent.

Patented May'16, 1916.

Application filed December 31, 1915. Serial No. 69,581.

T 0 all whom it may concern:

Be it known that I, IVILLIAM H. THOMP- soN, a citizen of the UnitedStates, residing at Marinette, in the county of Marinette and State ofWVisconsin, have invented a new and useful Car Attachment, of which thefollowing is a specification.

The device forming the subject matter of this application is adapted tobe employed upon cars or wagons of the sort used for the transportationof logs.

One object of the invention is to provide a novel form of stake, theconstituent members of which may be separated readily, to permit anunloading of the logs.

Another object of the invention is to provide novel means whereby theends of a chain or like flexible element may be detachably andreleasably united with the stakes intermediate the upper and lower endsof the stakes.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawing :Figure 1 shows in end elevation, a portionof a car or vehicle equipped with the device forming the subject matterof this application, parts appearing in section; Fig. 2 is'a perspectiveshowing a portion of the body of the car stake; Fig. 3 is a perspectiveshowing the base of the car stake; Fig. 4 is an elevation showing thelocking pin which unites the body of thestake with the base of thestake; Fig. 5 is a perspective showing a portion of the fasteningwhereby the ends of. a chain which extends between opposite stakes areconnected with the said stakes;.Fig. 6 is a perspective showing a.portionof'the structure delineated in Fig. 5, Fig. 6 illustrating anintermediate step in the process of releasing'the fastening shown inFig. 5; Fig. 7 is a perspective showing the releasing member used withthe fastening shown in Fig. 5; Fig. 8 is a side elevation showing thefastening of Fig. 5 in operative relation to the releasing means ofFig.7.

In carrying out the present" invention there is provided a car stakewhich is shown in Figs. 3, 2 and 1 of the drawings. The stake includes abody 1 ordinarily fashioned from wood. Applied to the lower end of thebody 1 is a cap 2 secured to the rear face of which is a reinforcingplate'3 .having a rearwardly projecting pin l. In one side of the cap 2there is formed a keyhole slot 5 having an upstanding extension 6. Adjacent its forward end the cap 2 is provided with laterally projectingstuds 7 The car stake includes a base 8 ordinarily made of wood. Appliedto the base 8 are side plates 9 upwardly extended to form a socket 10open at the frontand closed at the back. The side plates 9 may beconnected by a metal bottom 11' resting on the top of the base 8. In theforward edges of the socket 10 open notches 12 are formed. In the backof the socket 10 there is fashioned an opening 14. In one side of thesocket 10 there is a keyhole slot 15 including an extension 16 whichprojects upwardly. In the opposite side of the socket 10 there is a hole17 ordinarily of circular contour.

The numeral 18 designates a car or vehicle having eyes 19 at its sides.The bases 8 of the car stakes'are seated'in the eyes 19, the caps 2 ofthebody portions 1 of the stakes being received in the socket 10, thepins 4; registering in the openings 14, and the studs 7 being receivedin the notches 11. p

The connection between'the base 8 of the stake and the body 1 thereof isin the form of a pin 36 provided intermediate its ends with a lug 37 andequipped at one end with an angular arm 38. A flexible element 39 may beconnected to the arm 38. The arm 38 may be made to project upwardly,wheneupon the pin 36 is thrust through the registering keyhole slots 15and 5, thus to connect the body 1 with the base 8. The lug 37 then isfree to pass throughthe extensions 6 and 16 of the keyhole slots,Subsequently, the pin 36'is rotated by means of the arm 38, until thearm 38 extends downwardly, under which circumstances, the lug 37 willextend downwardly, also, and will look behind one side of the cap 2 atthe bottom of the keyhole slot 5, the free end of the pin 36 projectingoutwardly through the opening 17 in the socket 10.

The upper ends of the body portions 1 of opposed car stakes may beequipped with eyes 41, united by a chain, wire or other flexible elementshown at 40.

The numeral 20 indicates an intermediate connection, ordinarily in theform of a chain and provided at its ends with rings 30. lVith each ring30 is assembled a fastening whereby one end of the chain 20 is connectedwith the body 1 of the car stake. These fastenings are duplicates, andbut one of them need be described.

Each of the fastenings above alluded to embodies a flexible element 21provided at one end with a primary ring A secondary ring 23 is attachedto the other end of the flexible element. An intermediate ring 24 isconnected to the flexible element 21, between the ends of the flexibleelement, and relatively close to the ring 23. Pivoted at 25 to the ring23 is a lever 26 having a bend 27. The lever 26 passes through the ring22 1 as clearly shown in Fig. 5, and the bend 27 of the lever 26 engagesthe ring the free end of the lever 26 passing through the in termediatering 24. Pivoted at 28 to the free end of the lever 26 is a third ring29 which, cooperating with the ring 24, acts as keeper. lVhen thefastening shown in Fig. 5 is connected with the ring 30 and is extendedaround the body 1 of the car stake, it will be obvious that the carstake will be held to one end of the chain 20.

A releasing means is provided whereby the lever 26 may be uncoupledfrom. the rings 24 and 22. This releasing means is in the form of a link31 having eyes 32 at one end, the eyes 32 receiving an operating memherin the form of a chain or cord 33. At one end of the link 31 there isfashioned a bend 34 and intermediate its ends, the link is provided witha seat 35. When it is desired to release the fastening means shown inFig. 5, the third ring 29 is folded down onto the lever 26 and projectsthrough the intermediate ring 24 as best shown in Fig. 6 and as shown inFig. 8. lVhen the link 31 is passed through the intermediate ring 24,the bend 34 of the link 31 being detachably seated on the free end 28 ofthe lever 26, the seat 35 in the link 31 coacting with the intermediatering 24, and the lever 21 resting on the rihg 29, as shown in Fig. 8, sothat the ring 29 serves as a support for the lever 31. If, now, theflexible element 33 be drawn upon, the link 31 will be transformed intoa lever, the fulcrum of which is at the point where the bend 34 of thelink engages the free end 28 of the lever 26. l/Vhen the link 31 thus isoperated lever-wise, the free end of the link 24 is swung around to theright (Fig. 8) and is freed from the ring 29 and from the end of thelever 26. Thereupon the hold of the flexible element 21 around the body1 of the stake will be released.

In practical operation, the pins 36 first are withdrawn, .thusseparating the body portions 1 of the stakes from the bases 8 thereof.Subsequently, the ends of the chain 20 are detached from the bodies 1 ofthe stakes by the use of the device shown in Fig. 7, and finally, afterthe operations above described have been carried out, the logs will rolllaterally off the car 18, the body portions 1 of the stakes sliding inopposite directions off the bases 8 of the stakes. The function of theflexible element 40 which connects the tops of the stakes is to preventthe stakes from sliding downward into the logs as the logs are rolledoff the car. The ends of the flexible element 21 may be described asbranches of the tie or chain 20.
